In 1988-1989 two outbreaks of trichinosis were recorded. The first case was group disease developed in 3 members of the family. The source of infection was rissoles rolled in cabbage leaves [correction of goloubets] stuffed with minced pork. The second outbreak affected 13 persons who had eaten home-made pork sausage and fat. All the patients displayed fever, weakness, muscular pain, subcutaneous fat edema, predominantly of the face. The patients suffered from dry mouth, thirst, deteriorated appetite, exanthema, eosinophilia, more occasionally, nausea, vomiting, abdominal pain and diarrhea. Trichinosis was confirmed serologically. Vermox therapy (300 mg per day) was performed for 7 to 12 days. The disease was severe, moderate and mild in 5, 7 and 4 patients, respectively. A brief abstract from a case record of a patient with severe trichinosis complicated by allergic myocarditis is presented. The severity of the disease was associated with the infecting dose and the time at which etiotropic therapy was started. Vermox had a good therapeutic effect and caused no adverse events.

Trichinella spiralis infection was identified by direct fecal examination as the cause of gastrointestinal disease in a dog. The source of infection was believed to be a woodchuck. Management included supportive care and benzimidazole treatment. Vomiting, diarrhea, anorexia, and myalgia are the main signs of trichinosis, but routine fecal examination seldom reveals T spiralis in natural infections. Mebendazole is the recommended anthelmintic and should be used to eliminate intestinal larvae and prevent muscle invasion. Although the prevalence of trichinosis is decreasing in swine, wild mammals may still be a potential source for dogs and cats. Nevertheless, because of the nonspecific clinical signs of trichinosis, many cases probably go undiagnosed.

We sought to determine the effects of Trichinella spiralis infection on small intestinal motor activity in the fasted state in dogs and relate it to clinical symptoms during the intestinal phase of trichinosis. Motor activity was recorded by strain gauge force transducers. Infection with T. spiralis resulted in a significant increase in the incidence and proximal origination of giant migrating contractions (GMCs) during the first 5 days postinfection. This was also the time when the dogs had diarrhea. The dogs were often restless and showed signs of discomfort during proximally originating GMCs. The incidence of retrograde giant contractions (RGCs) increased significantly on the 2nd and 3rd day postinfection. RGCs were followed by vomiting 71% of the time during infection. The migrating motor complex cycle length increased significantly, and this was due to intestinal "amyogenesia" and "dysmyogenesia". During these phenomena, electrical control activity was almost completely obliterated in the proximal half of the small intestine (amyogenesia) and became irregular and unstable in the distal half (dysmyogenesia). Intestinal amyogenesia and dysmyogenesia lasted up to 4 h and were terminated by a GMC. We conclude that diarrhea induced by T. spiralis infection is closely associated with an increase in the incidence and proximal origin of GMCs. These GMCs may also be the motor correlates of abdominal cramping and pain during the intestinal phase of trichinosis.

Four patients had trichinosis after consuming raw home-butchered pork. The patients had fever, myalgias, periorbital edema, and conjunctivitis. All of the patients had nausea, vomiting, or diarrhea (corresponding to the intestinal phase of the infection) seven to ten days before the onset of fever and myalgias. Laboratory findings included eosinophilia, elevated serum CPK and aldolase values, and seroconversion of Trichinella serology one month after onset of myalgias. The patients were treated with mebendazole and prednisone and recovered uneventfully.

A 54-year old man was hospitalized with such acute complaints, as vomiting, fatigue, severe gastric pain, progressive weight loss. Gastric cancer was suspected, but the severity of the patient's state excluded X-ray examination of the stomach. The death occurred on day 9 of the hospital stay. It was only the microscopic pathoanatomic examination of the stomach and small intestine, that revealed trichinosis. Absence of Trichinella larvae in the gastric mucosa was suggestive of a massive alimentary infection in the patient.

Four outbreaks of human trichinellosis caused by eating pork together had occurred successively in two rural areas and two cities of Henan Province, where the disease is endemic. Of the 110 persons involved, 54 had the onset. All of them had the history of eating pork. In the outbreak of Dengzhou, in those persons who dined together, men were all uninfected and 13 women were infected. The difference found between sexes was suggested to be related with spirit drinking. In these 54 patients, the latent period ranged from 3 to 28 days. The relevant clinical symptoms and signs were fever, edema, myalgia, rash, headache, nausea, abdominal pain and diarrhea. Vomiting was uncommon. Most patients were hospitalized and all cases recovered in two weeks after proper treatment with albendazole.

Trichinellosis is caused by ingestion of insufficiently cooked meat contaminated with infective larvae of Trichinella species. The clinical course is highly variable, ranging from no apparent infection to severe and even fatal disease. We report two illustrative cases of trichinellosis. Returning to Denmark a few days after having eaten roasted pork in the Republic of Serbia, a female patient suffered from severe vomiting, epigastric pain, diarrhoea, and later myalgia, arthralgia, generalized oedema, and prostration. A biopsy showed heavy infestation with Trichinella spiralis, 2000 larvae/g of muscle. Life-threatening cardiopulmonary, renal and central nervous system complications developed. The patient recovered after several months. Her husband, who also ate the pork, did not have clinical symptoms, but an increased eosinophil count and a single larva in a muscle biopsy confirmed infection. The epidemiology, clinical manifestations, diagnosis, treatment and prevention of trichinellosis are reviewed.

The authors report a case of trichinosis acquired in Oklahoma City by an immigrant from Southeast Asia. The 49-year-old female reported having abdominal discomfort, nausea, and vomiting, and had purchased and eaten lightly cooked pork. She also complained of fatigue, anorexia, and muscle aches for several months. An immigrant from Laos, she stated that she regularly eats pork and prefers it rare or mildly cooked. The authors caution local physicians to be aware of the increased risk of trichinosis among Southeast Asian immigrants in the area, particularly those from Laos and Cambodia. Continued emphasis on the need to thoroughly cook all pork products is necessary if the incidence of trichinosis in the U.S. is to be controlled.

91 patients with trichinosis were treated at the Clinic of Infectious and Dermatovenereology Diseases in Novi Sad during a one-year period. In 64% of patients the onset was intestinal, while in 36% it was invasive. Diarrhea (in 28.89%) and abdominal pain (in 22.22%) are the most common symptoms of the intestinal stage. Nausea, vomiting and opstipation are less common. The main symptoms of the invasive stage are myalgia (65.54%), high temperature and eyelid edema (57.78%). Facial edema (38.89%), general weakness (24.44%), conjunctivitis (15.56%) and rash (8.89%) are somewhat less common. Heavy sweating, headache, nervousness, psychic instability and fast forgetting occur in a small number of treated patients. Myocarditis and encephalitis occurred in 3.33% of patients. There were 43.33% of patients with mild clinical picture, 40% with mild-to-severe and 16.66% with severe clinical picture. 54.44% of patients were males and 45.56% were females, and it can be said that sex did not influence the severeness of the clinical picture. The youngest patient was 5 years of age, the oldest 72. Most patients were 21-50 years of age but we did not establish statistical importance between clinical picture severeness in regard to age. The shortest period of incubation was 5 days, the longest 40 days. Average incubation period was 18.05 days (x = 18.05). Studying period of incubation and severeness of the clinical picture we established the following (x2 = 28.535). The shorter the incubation period, the severer the disease.

We report the case of a 42-year-old woman who was admitted to the hospital for fever, chills, nausea, vomiting, fatigue, myalgia, and general muscle weakness. All these symptoms had occurred 3 weeks after the ingestion of inadequately cooked pork meat, subsequently confirmed to be infested with Trichinella spiralis. Laboratory results showed mild leukocytosis, inflammation, and mild liver and muscle cytolytic syndrome, all suggestive of trichinellosis. Echocardiography showed apical hypokinesis and an apical mass (likely a thrombus). The immunologic assessment for the presence of Trichinella antigens was positive. The outcome was favorable after treatment with an anticoagulant, an antiaggregant, prednisone, and mebendazole. Follow-up controls showed the absence of any symptoms and thrombus, with only mild electrocardiogram modifications still present.
